In a large bowl, coat the chicken thighs thoroughly with 80ml of Peri-Peri sauce and marinate in the refrigerator for at least 4 hours.
Preheat the grill or a griddle pan to medium-high heat.
Place chicken on the grill and cook for 25-30 minutes, turning occasionally and basting with the remaining Peri-Peri sauce until the internal temperature reaches 74 degrees Celsius.
While the chicken is cooking, heat olive oil in a large saucepan over medium heat.
Sauté the onion, garlic, and red bell pepper for 5 minutes until softened.
Stir in the rice, turmeric, and smoked paprika, coating the grains in the oil and spices.
Add the chicken stock and bring to a boil; reduce heat to low, cover, and simmer for 15-18 minutes.
Stir in the frozen peas during the last 3 minutes of rice cooking time.
Fluff the rice with a fork and serve immediately alongside the grilled chicken.
Garnish with lemon wedges and fresh cilantro.
